DETAILED DESCRIPTION

FIGS. 1 through 5, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably-arranged system or device.

Remote sensing is the acquisition of information about an object without making physical contact with the object. Generally, remote sensing refers to use of an aerial vehicles (such as a satellite or aircraft) to detect and classify objects on earth. In certain embodiments, remote sensing is performed by an aerial vehicle that emits signals that are reflected off the surface of the earth, or an object between the aerial vehicle and the earth, and the reflected signals are detected by the aerial vehicle. For example, the aerial vehicle can emit energy in order to scan objects and areas and a sensor detects and measures the signals that are reflected back from the target. For instance, the signals can be in the form of Radio Detection And Ranging (RADAR) and Light Imaging Detection and Ranging (LIDAR). In certain embodiments, remote sensing can include radio frequency and hyperspectral sensing. Hyperspectral sensing is the generation of images by collecting and processing information across the electromagnetic spectrum. Hyperspectral sensing obtains a spectrum of electromagnetic waves for each pixel of the generated image. Hyperspectral sensing assists in identifying materials and object detection processes. In certain embodiments, remote sensing is performed by an aerial vehicle that captures sunlight that is reflected off of the surface of the earth, or an object between the aerial vehicle and the earth. For example, a sensor on an aerial vehicle can gather radiation that is emitted or reflected by the object or surrounding areas. The radiation can be sunlight.

Various observational satellites are in orbit around the earth. An observational satellite performs remote sensing to capture and record various information about the surface of the earth as well as objects between the satellite and the surface of the earth, such as clouds. Observational satellites can be located in a low earth orbit that circles the earth at a predefined interval, such as one revolution every 90 minutes. Satellites in a low earth orbit can often capture data of the same area of earth every time the satellite passes over the same area via remote sensing. Observational satellites can also be located in a geostationary orbit. A geostationary orbit revolves around the earth at the same rate as the earth rotates. To an observer on earth, a satellite in a geostationary orbit appears motionless.

Remote sensing data from aerial vehicles such as satellites are increasingly available. The high cadence of observational satellites in a low earth orbit provides large quantities of information such as the ability to detect changes for both military and civilian use. For example, in the case of a natural disaster, the ability to detect where damage is, the location of the most damage, safe and unobstructed ingress and egress can directly expedite and improve recovery efforts. However, the interpretation and analysis the data acquired from remote sensing data is difficult to generate due to the processing demands based on the size and quantity of the available data. Further, such data is often unstructured and difficult to extract useful insights. As such, a neural network can be used in the analysis of remotely sensed data.

A neural network is a combination is hardware and software that is patterned after the operations of neurons in a human brain. Neural networks are ideal at solving and extracting information from complex signal processing, pattern recognition, or pattern production. Pattern recognition includes the recognition of objects that are seen, heard, or felt.

Neural networks process and handle information very differently than conventional computers. For example, a neural network has a parallel architecture. In another example, how information is represented, processed, and stored by a neural network also varies from a conventional computer. The inputs to a neural network are processed as patterns of signals that are distributed over discrete processing elements, rather than binary numbers. Structurally, a neural network involves a large number of processors that operate in parallel and are arranged in tiers. For example, the first tier receives raw input information and each successive tier receives the output from the preceding tier. Each tier is highly interconnected, such that each node in tier n can be connected to many nodes in tier n−1 (such as the nodes inputs) and in tier n+1 that provides input for those nodes. Each processing node includes a set of rules that it was originally given or developed for itself over time.

A convolutional neural network is a type of a neural network that is often used to analyze visual imagery. A convolutional neural network is modeled after the biological process of vision in which individual cortical neurons respond to stimuli only in a restricted region of the visual field. The restricted region of the visual field is known as the receptive field. The receptive fields of different neurons partially overlap such that in totality the many neurons cover the entire visual field. Similarly, in a convolutional neural network, each convolutional neuron processes data that is limited to the neuron's respective field.

Neural networks (as well as convolutional neural networks) are often adaptable such that a neural network can modify itself as the neural network learns and performs subsequent tasks. For example, initially a neural network can be trained. Training involves providing specific input to the neural network and instructing the neural network what the output is expected. For example, if the neural network is to identify a city infrastructure, initial training can include a series of images that include city infrastructure and images that do not depict city infrastructure, such as persons, animals, and plants. Each input (city infrastructure, persons, animals, and plants) includes a detail of the infrastructure or an indication that the object is not city infrastructure. By providing the initial answers, this allows a neural network to adjust how it internally weighs a particular decision to improve how to perform a given task. For example, to identify city infrastructure it could be necessary to train a neural network for each particular city. In another example, to identify city infrastructure it could be necessary to train a neural network for types of cities such as rural cities, urban cities, and the like. In another example, to identify city infrastructure it could be necessary to train a neural network based on geographic areas around a city. For instance, a city having a grid-like layout appears differently than a city that follows a natural landmark such as a river or a mountain.

The architectures of a neural network provide that each neuron can modify the relationship between its inputs and its output by some rule. The power of a particular neural network is generated from a combination of (i) the geometry used for the connections, (ii) the operations used for the interaction between neurons, and (iii) the learning rules used to modify the connection strengths, to name a few.

Neural networks are trained to perform specific tasks, as well as given specific types of input data. Due to the various geographical data that can be acquired by remote sensing, neural networks are not scalable to perform the analysis of general input data to produce specific results. Embodiments of the present disclosure provide for an adaptive neural network selection to extract particular results, based on particular input data. Embodiments of the present disclosure provide a neural network framework that adaptively adjusts to overcome various regional and sensor based dependences of a neural network. In certain embodiments, the neural network framework can detect change of remote sensed data of a given location not limited to particular geographic areas. In certain embodiments, the neural network framework can provide infrastructure identification that is not limited to particular geographic areas. Similarly, in certain embodiments, the neural network framework can provide water detection as well as non-water based objects where the analysis is not limited to particular geographic areas.

FIG. 1 illustrates an example computing system 100 according to this disclosure. The embodiment of the system 100 shown in FIG. 1 is for illustration only. Other embodiments of the system 100 can be used without departing from the scope of this disclosure.

The system 100 includes network 102 that facilitates communication between various components in the system 100. For example, network 102 can communicate Internet Protocol (IP) packets, frame relay frames, Asynchronous Transfer Mode (ATM) cells, or other information between network addresses. The network 102 includes one or more local area networks (LANs), metropolitan area networks (MANs), wide area networks (WANs), all or a portion of a global network such as the Internet, or any other communication system or systems at one or more locations.

The network 102 facilitates communications between a server 104, a satellite 116, and various client devices 106-114. The client devices 106-114 may be, for example, a smartphone, a tablet computer, a laptop, a personal computer, a wearable device, or a head-mounted display (HMD). The server 104 can represent one or more servers. Each server 104 includes any suitable computing or processing device that can provide computing services for one or more client devices. Each server 104 could, for example, include one or more processing devices, one or more memories storing instructions and data, and one or more network interfaces facilitating communication over the network 102.

The satellite 116 is an object located in orbit around the earth. Satellite 116 can be an observation satellite, a communication satellite, a navigation satellite, a meteorological satellite, a space telescope, and the like. Depending on the type of satellite, satellite 116 can include a variety of instruments such as imaging, telecommunications, navigation, and the like. The satellite 116 can receive and transmit data from server 104 or any client device 106-114. In certain embodiments, satellite 116 can be any aerial vehicle such as a drone, an airplane, a helicopter, a high altitude balloon, and the like.

Each client device 106-114 represents any suitable computing or processing device that interacts with at least one satellite, one server or other computing device(s) over the network 102. In this example, the client devices 106-114 include a desktop computer 106, a mobile telephone or mobile device 108 (such as a smartphone), a personal digital assistant (PDA) 110, a laptop computer 112, and a tablet computer 114. However, any other or additional client devices could be used in the system 100.

In this example, some client devices 108-114 communicate indirectly with the network 102. For example, the client devices 108 and 110 (mobile devices 108 and PDA 110, respectively) communicate via one or more base stations 118, such as cellular base stations or eNodeBs (eNBs). Also, the client devices 112 and 114 (laptop computer 112, and tablet computer 114, respectively) communicate via one or more wireless access points 120, such as IEEE 802.11 wireless access points. Note that these are for illustration only and that each client device 106-114 could communicate directly with the network 102 or indirectly with the network 102 via any suitable intermediate device(s) or network(s), such as base stations 118, access points 120.

Although FIG. 1 illustrates one example of a system 100, various changes can be made to FIG. 1. For example, the system 100 could include any number of each component in any suitable arrangement. In general, computing and communication systems come in a wide variety of configurations, and FIG. 1 does not limit the scope of this disclosure to any particular configuration. While FIG. 1 illustrates one operational environment in which various features disclosed in this patent document can be used, these features could be used in any other suitable system.

The processes and systems provided in this disclosure allow for the satellite 116 to capture images of the earth and transmit the images to the server 104 or any client device 106-114, or a combination thereof for processing. Images can include various types of remote sensing such as spatial, spectral, temporal, and radiometric. For example, spatial resolution is the pixel size of an image representing the size of the surface area that is measured on the ground as determined by the instantaneous field of view of the sensor. Spectral resolution is the wavelength interval size such as the discrete segment of the Electromagnetic Spectrum coupled with the number of intervals that the sensor is measuring. Temporal resolution is the amount of time that passes between imagery collection periods of a specific surface location. Radiometric resolution is the ability of an imaging system to record many levels of brightness, such as contrast, and to the effective grayscale or bit-depth of the sensor. The imaging capability of the satellite 116 can be limited by geometric resolution. Geometric resolution refers to the ability of the satellite 116 to effectively image a portion of the surface of the earth in a single pixel. The geometric resolution is typically expressed in terms of Ground sample distance (GSD). GSD is a term containing the overall optical and systemic noise sources and is useful for comparing how well one sensor can “see” an object on the ground within a single pixel. For example, the GSD can range from 0.41 meters to 30 meters depending on the ability of the satellite 116. For instance, if the GSD is 30 meters, then a single pixel within an image is approximately 30 meters by 30 meter square. The satellite 116 can be located in any orbit such as the low earth orbit, the polar orbit, and a geostationary orbit.

For example, electronic device 300 can be a computer (similar to the desktop computer 106 of FIG. 1), a mobile device (similar to the mobile device 108 and the PDA 110 of FIG. 1), a laptop computer (similar to the laptop computer 112 of FIG. 1), a tablet computer (similar to the tablet computer 114 of FIG. 1), and the like. In certain embodiments, the electronic device 300 can be multiple computing devices connected over a medium such as a network (similar to network 102 of FIG. 1). For example, each neural network (neural network 340A, neural network 340B) can be located on separate computing devices.

Information repository 310 can be similar to memory 260 of FIG. 2. In certain embodiments, information repository 310 is similar to remote sensing data 263 of FIG. 2. Information repository 310 can store one or more images. In certain embodiments, images can include various types of remote sensing such as spatial, spectral, temporal, and radiometric. In certain embodiments, images can include images captured by a variety of wavelengths, such as radio waves, microwaves (such as RADAR), infrared waves (such as thermal imagery), the visible spectrum (such as color and black and white images), ultraviolet waves, X-rays, gamma rays, magnetism, and the like. In certain embodiments, images can include images generated by hyperspectral imaging. In certain embodiments, images can include images generated by radio frequency imaging. In certain embodiments, the images include heterogeneous image data set. Data stored in information repository 310 includes various images originally captured from various aerial vehicles. Information repository 310 can maintain metadata associated with each image. In certain embodiments, the metadata can indicate the capturing source of the data, the geographical location of the data, resolution, sensor type, and the like. In certain embodiments, the electronic device can generate additional metadata that statistically describes the received image data. The generated metadata can also be maintained in the information repository 310.

In certain embodiments, remote sensing data within the information repository 310 include a set of aerial images. The aerial images can be captured from a satellite as the satellite passes over a position of the earth. The aerial images can be captured from an aerial vehicle such as a drone or airplane or both, as the aerial vehicle passes over a position of the earth. The remote sensing data can include color images, and black and white images. The remote sensing data can comprise images originating from one or more radio frequency bands. The remote sensing data has a resolution that defines the clarity and details of the content of the image. The remote sensing data can also include a histogram that provides details of the image.

Transform engine 320 analyzes the image using one or more transforms to extract data from the image. In certain embodiments, the transform engine 320 utilizes image frequency transformations such as the Discrete Cosine Transform (DCT), Hadamard Transform, Fourier Transform, and the like. In certain embodiments, the transform engine 320 utilizes texture analysis. In certain embodiments, the transform engine 320 reduces ground truth data requirements for later processing, such as machine learning or processing by a neural network, or both.

The DCT represents an image as a sum of sinusoids of varying magnitudes and frequencies. In certain embodiments, the DCT separates an image into parts of differing importance. The DCT is similar to a Fourier Transform that decomposes a function of time, such as a signal into various frequencies. Similarly, the Hadamard Transform is a class of Fourier Transform. In certain embodiments, the output of the transform can be a frequency domain while the input image is in the spatial domain. A Fourier Transform is utilized to access geometric characteristics of a spatial domain image. In certain embodiments, a correlation is created between an image that results from a frequency transform and parameters associated with a neural network. For example, the correlation can include convolution kernel size, number of layers, stride, and the like. The transform engine 320 deconstructs an image or a set of images. In certain embodiments, the transform engine 320 deconstructs an image in order to generate metadata that can describe the image as well.

In certain embodiments, the transform engine 320 reduces the requirements of ground truth when the images are presented to at least one of the neural networks 340. For example, by manipulating the image by one or more transforms, various data can be extracted. In another example, by manipulating the image by one or more transforms, a texture analysis of the remote sensing data can be performed. A texture analysis can be performed using various frequency transoms such as DCT, a Fourier transform, and Hadamard in order to capture various characteristics of the texture that repeats. In certain embodiments, the Fourier Transform is a Fast Fourier Transform (FFT). In certain embodiments, following the various frequency transforms a clustering algorithm is applied to the remote sensing data (such as an image) to classify the various textures. For example, the algorithm used to classify the various textures is a neural network such as one of the neural networks 340. In another example, the neural network 340A can classify the remote sensing data following the transform based on a describing texture technique such as a bubbly, a lined, a checkered, and the like. In certain embodiments, the transform engine 320 performs a texture analysis to provide pre-processing image segmentation, ground truth, accelerated neural network training, and the like.

The machine learning engine 330 analyzes the image to provide an initial assessment of the image. The machine learning engine 330 is provided the results from the transform engine 320. The machine learning engine 330 detects metadata associated with the image as well as features of the image itself. The machine learning engine 330 makes simple and quick decisions that identify one or more features of the image. Stated differently, the machine learning engine 330 detects and identifies objects in the image without any ground truth data of the image. In certain embodiments, the machine learning engine 330 can predict features within the image.

The machine learning engine 330 analyzes the image and generates metadata that describes the image. The generated metadata that describes the image can include coefficients and statistics. In certain embodiments, the machine learning engine 330 utilizes computer vision to extract information about one or more objects within the image or one or more aspects about the image. For example, machine learning engine 330 identifies objects within the image using object recognition processing. In certain embodiments, the machine learning engine 330 generates at least one prediction as to the content within the image. The prediction can be used by the neural network selection program 350 to select a particular neural network.

In certain embodiments, the machine learning engine 330 is unsupervised, in that no ground truth is provided to the machine learning engine 330 as to what objects might be in the image. For example, if the image is an aerial view of an ocean, the machine learning engine 330 determines whether the image is of the ocean based on metadata associated with the image or from the image transform. The machine learning engine 330 can determines that the image is blank. That is the, image is unrecognizable by the machine learning engine 330. The machine learning engine 330 can determine that the image is of the sky taken from the surface of the earth looking upwards. That is the image appears to be the sky. For example, the machine learning engine 330 can interpret the uniform color of the ocean and white waves as the sky with clouds. The machine learning engine 330 can determine that the image is of the ocean. In certain embodiments, the machine learning engine 330 can determine the exact location on earth that the image is of, based on metadata associated with the image when the image was captured, such as geospatial location. Regardless of the outcome of the decision, the machine learning engine 330 makes one or more decisions about the image itself without input as to what the image contains.

In another example, if the inputted image is an aerial view of an area of land, the machine learning engine 330 attempts to derive information about the image. The machine learning engine 330 can identify that the image is of an aerial view of a city. The machine learning engine 330 can identify features of the environment, such as rivers, lakes, streams, mountains, deserts, and the like. The machine learning engine 330 can identify approximate ground temperature if the image includes thermal imaging. The machine learning engine 330 can identify vegetation. For example, the machine learning engine 330 can identify vegetation based on the colors of the image. For instance, if the color green is prevalent, then the machine learning engine 330 can identify features of vegetation, by associating the color green with vegetation.

Neural networks 340 is a repository of two or more neural networks, such as neural network 340A, neural network 340B, through neural network 340N. In certain embodiments, each neural network 340A-N is a convolutional neural network. A convolutional neural network is made up of neurons that have learnable weights and biases. Each neuron receives an input and performs a decision. A convolutional neural network makes an explicit decision that any input is an image. For example, the architecture of each neural network 340A-N is arranged in three-dimensions, such that each neural network 340A-N is a volume.

In certain embodiments, each neural network 340A-N is a generalized neural network that is pre-trained. For example, each neural network 340A-N is pre-trained and specialized to perform a particular task based on a given input. The more training each neural network 340A-N undergoes the more accurate the results are. It is noted that the more training each neural network 340A-N undergoes the narrower the field of analysis is. For example, neural networks 340A-N can be pre-trained to identify infrastructure of a city. For instance, neural network 340A can detect and identify industrial buildings within a city. Similarly, neural network 340B can detect and identify residential houses within a city. Neural network 340B can be trained to identify residential and industrial buildings. For example, to identify and distinguish between residential and industrial buildings, neural network 340B can identify the roof type or the roof shape.

In another example, each neural network 340A-N can be pre-trained to identify changes to a city's infrastructure over a period. For instance, neural network 340A can be pre-trained to identify buildings that change over a period of time. Similarly, neural network 340B can be pre-trained to identify changes to water location within a city. Changes in water location can be useful in order to detect if flooding that occurred and if so locations as to where water has encroached into the city. Similarly, neural network 340C can be pre-trained to identify changes to roads. Changes to roads can be useful in detecting damage after a natural disaster to plan ingress and egress to areas of the city.

In another example, each neural network 340A-N can be pre-trained to identify certain material within an image. For instance, the neural network 340A can be trained to identify aluminum within an image. Similarly, neural network 340B can be pre-trained to identify areas of water and areas of non-water within an image.

Neural network selection program 350 selects a particular neural network to perform a given task based on the input data within the information repository 310. Since each neural network 340A-N is designed to perform specific tasks, the neural network selection program 350 can select a neural network to perform a given task, based on generated data from the transform and the machine learning as well as metadata that is included with the image itself.

In certain embodiments, the neural network selection program 350 analyzes the generated metadata from the machine learning engine 330 that identified various features in the image. Based on the identified features, the neural network selection program 350 can select a particular neural network such as neural network 340A-N to perform and extract information from the image.

In certain embodiments, neural network selection program 350 analyzes the generated metadata from the machine learning engine 330 to identify features within the remote sensed data. Based on the identified features, the neural network selection program 350 can select a particular neural network from the neural networks 340 based on the identified features of the remote sensed data. The neural network selection program 350 selects a particular neural network from the neural networks 340 that is trained to analyze features of the image. Since the transform engine 320 removes an element of ground truth, and the machine learning engine 330 identifies features of the image, the neural network selection program 350 can autonomously or near autonomously select a particular neural network from the neural networks 340 to perform the analysis on the image. In certain embodiments, the features of the image that the neural network selection program 350 identifies and analyzes when selecting a particular neural network includes an identified object of the image by the machine learning engine 330.

In certain embodiments, the features of the image that the neural network selection program 350 identifies and analyzes when selecting a particular neural network includes metadata generated when the remote sensing data was captured. For example, the geospatial location of the remote sensed data can include the location on earth of where the image is located. The location of the captured data can indicate whether the image is of a city, farm land, an urban area, a rural area, a city in a first world country, a city in a third world country, a body of water, a natural landmark, a desert, a jungle, and the like. If the geospatial location of the image indicates a city, the geospatial location can provide the neural network selection program 350 the name of the city, the age of the city, country the city is located in and the like. Such information can provide an indication of common building materials of the city and an estimation of the city layout, in order for the neural network selection program 350 to select a trained neural network that specializes in analyzing the remote sensed data of the sort. For example, a newer city may have a grid like pattern and use particular materials for the roofs and various city infrastructure buildings. In another example, an older city may follow a natural feature such as a river that prohibits a grid like city structure. Additionally, older cities may use older materials for roofs, and infrastructure. In certain embodiments, the neural network selection program 350 can utilize the generated metadata from the machine learning engine 330 to sub-classify a city. For example, the city can be sub-classified into a town, a metro area, rural area, suburban area as well as include a differentiation between industrial and residential buildings. In another example, the areas city can be sub-classified into construction, demolition and the like.

For example, if the task assigned to a neural network is to detect change of an infrastructure such as damage caused by a natural disaster, by identifying the type of content within the remote sensed data the neural network selection program 350 can select a neural network that is trained to detect damage. For instance, if the geospatial location indicates that an image is of a city, then a particular neural network can be selected that distinguishes from construction and damage. In another instance, if the geospatial location indicates that the image is of a rural area, then a particular neural network can be selected that distinguishes from farmland and damage.

If the geospatial location of the remote sensed data can indicate a body of water, the geospatial location can provide the neural network selection program 350 as to the type of water (an ocean, a sea, a lake, a river, and the like). The geospatial location that indicates a body of water can also indicate whether the water is sea water, brackish water, or fresh water. The geospatial location can also indicate whether land masses are near the body of water. For example, if the geospatial location of the remote sensed data does not have a landmass in proximity, the neural network selection program 350 can select a neural network that analyzes for particular structures, shapes, materials. For instance, if the task presented to the neural network selection program 350 is to find a particular shape or material, such as debris from an airplane or boat that crashed in the body of water, then the neural network selection program 350 selects a particular neural network that is trained to detect particular shapes or materials.

In certain embodiments, the features of the image that the neural network selection program 350 identifies and analyzes when selecting a particular neural network includes one or more parameters associated with the machine learning engine 330. The parameters associated with the machine learning engine 330 can include a clustering methodology, as well as number of clusters. Clustering methodology can include K means and principal component analysis (PCA). K-means is a non-parametric method that can be used in classification and regression modeling.

In certain embodiments, the features of the image that the neural network selection engine program identifies and analyzes when selecting a particular neural network includes the manipulated remote sensed data from the image transform engine 320. In certain embodiments, the features of the remote sensed data that the neural network selection program 350 identifies and analyzes when selecting a particular neural network includes the remote sensed data prior to the manipulation by the transform engine 320. For example, the neural network selection program 350 can receive the manipulated remote sensed data or the original remote sensed data, or a combination thereof. When the neural network selection program 350 receives and analyzes the manipulated remote sensed data, various hidden features of the remote sensed data are revealed and allow the neural network selection program 350 to select a particular neural network that is trained to handle the particular remote sensed data. For example, the neural network selection program 350 can associate the particular transform used, the extract data from the transform, a convolutional kernel size, a number of layers, the stride of each of the neural networks 340, in selecting a particular neural network.

FIGS. 4A-4B illustrate an example neural network selection process in accordance with an embodiment of this disclosure. FIGS. 4A and 4B illustrate environment 400A and 400B, respectively, depicting a neural network selection. FIG. 4B is a continuation of FIG. 4A. The embodiments of the environment 400A and 400B shown in FIGS. 4A and 4B are for illustration only. Other embodiments could be used without departing from the scope of the present disclosure.

Sensor metadata 402 of FIG. 4A is metadata that indicates various aspects of the image data 404. Similarly, sensor metadata 406 of FIG. 4A is metadata that indicates various aspects of the image data 408. Metadata 410 of FIG. 4A is metadata that indicates various aspects of the image data 412. The sensor metadata 402, 406, and 410 includes metadata of the capturing source of the image data 404, 408, and 412 respectively. The sensor metadata 402, 406, and 410 can include the geographical location of the data, resolution, sensor type, type of sensor, the mode of acquisition (satellite, type of aerial vehicle and the like), to name a few. The image data 404, 408, and 412 can be remote sensing data. The image data 404, 408, and 412 can be from the same source or different sources. The image data 404, 408, and 412 can each be one or more aerial image(s) of various locations of the earth. For example, image data 404 can be of a city, image data 408 can be image data taken of a particular ocean, and image data 412 can be an image of a desert. In another example, image data 404, 408, and 412 can be of the same location on earth, such as a particular city taken at various time intervals. In another example, image data 404, 408, and 412 can be a hyperspectral image, that includes information across the electromagnetic spectrum.

Each respective image data is manipulated by a transform such as transform 422, 424, 426, and 428. Transform parameters 420 as well as transforms 422, 424, 426, and 428 are similar to the transform engine 320 of FIG. 3. In certain embodiments, transform 422 is applied to image data 404, 408, and 412. Transform parameters 420 include can include a kernel size, a stride, a transform type, or a combination thereof. The transform type can include a discrete cosine transform, a local binary pattern transform, a Fourier Transform, and the like. The local binary pattern transform is a type of visual descriptor used for classification in computer vision. That is, the local binary pattern transform is a texture spectrum model for texture classification of images via remote sensed data. In certain embodiments, the local binary pattern transform can be combined with the histogram of oriented gradations to improve the classification. In certain embodiments, each image data 404, 408, and 412 are not limited to only the transforms of 422, 424, 426, and 428. Rather, any number of transforms can be applied to each image. That is, more transforms (not shown) as well as less transforms can be applied to each image such as image data 404, 408, and 412.

Once an image data passes through a transform (such as transform 422, 424, 426, and 428) on environment 400A, the transformed image data is transmitted to a machine learning 432, 434, 436, and 438 of environment 400B, respectively. That is, image data 404 can pass through any number of transforms (such as transform 422, 424, 426, and 428) on environment 400A and then each transformed version of image data 404 is passed to the machine learning 432, 434, 436, and 438 of environment 400B, respectively. Machine learning parameters 430 as well as machine learning 432, 434, 436, and 438 are similar to the machine learning engine 330 of FIG. 3.

In certain embodiments, when more or less transforms are present, a respective number of machine learning 432, 434, 436, and 438 are present. For example, when more transforms are present, more machine learnings are present.

In certain embodiments, the machine learning parameters 430 can include various clustering methodologies such as K-means and PCA. In certain embodiments, the machine learning parameters 430 can also include a number of clusters. In certain embodiments, the machine learning parameters 430 detect patterns within the image in order to predict the content of the image. For example, each machine learning 432, 434, 436, 438 can analyze the same image that was manipulated by a transform (such as transform 422, 424, 426, and 428) in order to extract various patterns of the image.

Analyzer 440A, 440B, 440C, and 440D analyzes the results of the machine learning 432, 434, 436, and 438 respectively. Analyzer 440A includes analytics 442A, sensor metadata 444A, transform parameters 446A, and machine learning parameters 448A. Similarly, analyzer 440B includes analytics 442B, sensor metadata 444B, transform parameters 446B, and machine learning parameters 448B. Similarly, analyzer 440C includes analytics 442C, sensor metadata 444C, transform parameters 446C, and machine learning parameters 448C. Similarly, analyzer 440D includes analytics 442D, sensor metadata 444D, transform parameters 446D, and machine learning parameters 448D. Analytics 442A, 442B, 442C, and 442D are similar. Sensor metadata 444A, 444B, 444C, and 444D are similar. Transform parameters 446A, 446B, 446C, and 446D are similar. Machine learning parameters 448A, 448B, 448C, and 448D are similar.

Analytics 442A, 442B, 442C, and 442D can include various features of the image data as derived by the machine learning 432, 434, 436, and 438, respectively. For example, analytics 442A, 442B, 442C, and 442D can include buildings, roads, infrastructure, and the like. In another example, analytics 442A, 442B, 442C, and 442D can include analyzing different time stamps of the image to detect change.

Sensor metadata 444A, 444B, 444C, and 444D is similar to the sensor metadata 402, 406, or 410. For example, sensor metadata 444A is the sensor metadata 402, 406, or 410 that is associated with the image that was received by machine learning 432. The image that was received by machine learning 432 can be image data 404, 408, or 412. The sensor metadata 444A, 444B, 444C, and 444D can include a satellite image source, a resolution, a sensor type and the like.

Transform parameters 446A, 446B, 446C, and 446D are similar to the transform parameters 420. Transform parameters 446A, 446B, 446C, and 446D analyze the kernel size, stride, and the transform type (such as discrete cosine transform, a local binary pattern transform, a Fourier Transform, and the like).

Machine learning parameters 448A, 448B, 448C, and 448D are similar to the machine learning parameters 430. Machine learning parameters 448A, 448B, 448C, and 448D analyze the clustering methodology (such as K-means, PCA and the like) and the number of clusters.

Analyzer 440A, 440B, 440C, and 440D analyzes the input data from each element and the information is passed to the neural network selection 450. Neural network selection 450 is similar to the neural network selection program 350 of FIG. 3. The neural network selection 450 selects a particular neural network to perform the analysis on the received image data 404, 408, or 412.

FIG. 5 illustrates a method for selecting a neural network in order to extract particular results from images in accordance with an embodiment of this disclosure. FIG. 5 does not limit the scope of this disclosure to any particular embodiments. While process 500 depicts a series of sequential steps, unless explicitly stated, no inference should be drawn from that sequence regarding specific order of performance, performance of steps or portions thereof serially rather than concurrently or in an overlapping manner, or performance of the steps depicted exclusively without the occurrence of intervening or intermediate steps.

For ease of explanation, the method of selecting a particular neural network is performed with respect to the server 104 of FIG. 1, any of the client devices 106-114 of FIG. 1, the electronic device 200 of FIG. 2, or the electronic device 300 of FIG. 3. However, the process 500 can be used with any other suitable system, or a combination of systems.

In block 502 the electronic device receives remote sensed data. The remote sensed data can be received from an aerial vehicle or a satellite. The remote sensed data can include an image. The remote sensed data can include a set of images. The remote sensed data can be aerial images. In certain embodiments, the remote sensed data can include a color image, or a black and white image. In certain embodiments, the remote sensed data can be captured based on at least one radio frequency bands that include visible and non-visible bands. The remote sensed data can also include a resolution and histogram.

In block 504 the electronic device transforms the remote sensed data. The transform can include at least one signal processing transform such as a Fourier Transform, a Discrete Cosine Transform, a Hadamard Transform, and the like. By processing the image with a transform, various aspects of necessary ground truth of the image can be reduced.

In block 506 the electronic device analyzes the transformed image in order to generate metadata. In certain embodiments, the analysis of the transformed image is performed by machine learning. In certain embodiments, the machine learning is unsupervised. The generated metadata statistically describes the received remote sensed data. In certain embodiments, the analysis of the transform image is performed by a machine learning engine, similar to the machine learning engine 330 of FIG. 3. The analysis of the transformed image provides a prediction as to the content in the image.

In block 508 the electronic device selects a particular neural network to perform a second analysis of the received remote sensed data. In certain embodiments, the selection of a particular neural network is based on the generated metadata from block 506. The selecting of a particular neural network can be based on various metadata received with the remote sensed data, transform parameters, machine learning parameters, as well as analytics. The metadata that is received with the remote sensed data can include generated data that indicates parameters of the sensor's capability when the remote sensed data was acquired, such as a geospatial location of the content of remote sensed data, a listing of the radio frequency bands within the remote sensed data, a resolution, a histogram and the like. In certain embodiments, the selection of a particular neural network is based on an identified object based on the analysis of block 506. In certain embodiments, the selection of a particular neural network is based on various machine learning parameters. In certain embodiments, the selection of a particular neural network is based on the manipulated image data from block 504.

In block 510 the electronic device performs a second analysis by the selected neural network of block 508. The second analysis is performed to extract data from the received remote sensed data. The second analysis can include loss data that is domain specialized. In certain embodiments, the loss data is based on prior approaches to semantic segmentation.

The second analysis detects and classifies various aspects of the content within the remote sensed data. For example, the second analysis detects infrastructure of an area. In another example, the second analysis can perform a change detection of the infrastructure of the area.

In certain embodiments, the extract data can be compared to the generated metadata from block 506. Based on the comparison, the results can be input into the selected neural network to improve the training of the neural network. For example, particular neural network was selected (block 508) based in part on the predicted results of the first analysis (block 506). If the predictions from block 506 are not accurate, the selected neural network can be trained to accommodate the inaccurate prediction to improve the results generated by the selected neural network. Similarly, if the predictions from block 506 are accurate, then the selected neural network can be trained to improve the results as well as trained to skip portions of the processing to increase speed and efficiency.

In certain embodiments, process 500 initially processes the input data using unsupervised image processing and remote sensing techniques. Image processing and remote sensing techniques can include Discrete Cosine Transform to reduce ground truth requirements, accelerate training, improve performance for the selected use case by implicating certain pertained models as ideal candidates by narrowing the number of neural networks, or a combination thereof. A domain specialized loss function can be implemented based on prior approaches in order to perform semantic segmentation to increase prediction confidence by a machine learning, or increase the learning rate of each neural network, or a combination thereof. By using selection of generalized neural networks that can leverage various pre-trained models to transfer learning to scale the inference of multiple resolutions of imagery and remote sensing data from different types of sensors, allows various neural networks to be adapted to the input data. Similarly, the neural networks can be selected based on the input data to provide a neural network system than can scale and process a variety of input data sources with limited ground truth availability. In certain embodiments, the various neural networks are convolutional neural networks with the capability of extracting features from remote sensed data and imagery. For example, the selection and initialization of one or more neural networks is tailored to the specific input and a desired outcome.

For example, the user equipment can include any number of each component in any suitable arrangement. In general, the figures do not limit the scope of this disclosure to any particular configuration(s). Moreover, while figures illustrate operational environments in which various user equipment features disclosed in this patent document can be used, these features can be used in any other suitable system.

The scope of patented subject matter is defined only by the claims.
